But, When i open TB. It goes swimmingly, until i click something or other, like, i can turn on a mod, and get halfway through a move, and it closes, it happens randomly... Any suggestions?

could be the mod, it may be unstable such as having to many env obj for your comp to handle or if you have shaders on it could always be some random problem with that...

i've downloaded 3 mods.. and i never have shaders on..

What mod does it ?
Can you post the contents of stderr.txt after it crashes with this mod ?
Thanks.

Im a retard, i have no idea what a stderr.txt is, sounds like a mockery of me or something lol, i just wiped TB off my comp and re-installed, did the trick

For the reference, stderr.txt is an error log that can be found in the Toribash directory.
